Network Analysis kiln cement production method is different from one, the characteristics of shaft kiln production process is simple, less investment, construction easier, fast convergence, covering small, low technical requirements, suitable for inaccessible areas, and thermal consumption is also low. Ordinary kiln heat consumption is 1000 ~ 1200Kcal/kg clinker, mechanical shaft kiln heat consumption is 800 ~ 1100Kcal/kg clinker, the minimum up 800Kcal/kg clinker, wet kiln heat consumption is equivalent to 1/2 to 1 / 3 (1Kcal ≈ 4.18KJ). However, this type of kiln generally lower yields, the quality is sometimes unstable. 2, wet kiln production characteristics of raw material containing 32% to 40% water slurry, raw material mixed, homogenized good, high quality, composition and stability, less environmental pollution, and eliminating the need for raw material drying equipment, but high heat consumption, usually 1500Kcal/kg clinker so. According to statistics, in the 1950s, a small wet kiln firing per kg of clinker requires only 1200Kcal calories, while a 7.5m × 231m although large wet kiln production to Taiwan up to 150t, but the heat consumption has risen to every kg clinker 1390Kcal. Is in the interior of the chain length of 37km, the exhaust gas temperature remains below 210 ℃, and thus the world's wet production has gradually been eliminated. 3, dry production features dry kiln is the late 18th century, early 19th century kiln type, because it uses the raw material is dry, water content <1% over the wet production reduced the majority of the heat is used to evaporate water , but also shorter than the wet process. But it demonstrated hot dry kiln utilization device, kiln temperature is generally 700 ~ 950 ℃, some plants can be seen flaming chimney phenomenon, serious waste heat, heat consumption of clinker per kg up to 1713 ~ 1828Kcal, and dusty, pollution, raw material homogenization poor, low quality, yield is not high (both compared with the wet production), was once wet production replaced. The early 1930s, there has been Lepol kiln, at the end of the kiln heating machine installation of a grate on the moisture content of 12% to 14% of the raw material is heated balls to make better use of waste heat, kiln temperature dropped from below 700 ℃ 100 ~ 150 ℃, heat consumption dropped substantially, yield and quality have been greatly improved. 20 world, the 1950s have emerged with cyclone preheater kiln, kiln better use of waste heat, especially the early 1970s with the emergence of a new type of kiln calciner kiln production line,Ball mill the dry production to a new phase. This low energy consumption, high yield, good quality, new technology has become the world's kiln cement production development. With cyclone preheater kiln and calciner kiln with kiln, not only to make up for the old dry production defects can not make good use of waste heat, but also by the heat consumption of clinker clinker fell 720 ~ 850Kcal/kg 1800Kcal/kg clinker. This type of kiln shell short, high yield, coupled with both chemical and biological materials using compressed air mixing, using various types of dust collectors eliminate pollution, so that in the production, quality, energy saving, environmental benefits and other aspects have a clear advantage. 4, the production of semi-dry kiln kiln feed feature will add water into the ball, before passing into the kiln heating grate heat exchange, so that up to 1000 ~ 1100 ℃ high temperature exhaust gas preheating of the material is dried and partially decomposed rate of up to about 30%, the material into the kiln temperature up to about 700 ℃ average, so low heat consumption, high yield.
